The header-cell is the header for a column with possibly many
rows.
We must not set:
header_cell->skip = nmc_config->overview && is_default;
for a particular cell, because it does not take into accound
the neighbouring rows. It is only correct, if there is only
one row.
Invert the logical meaning and rename "strip" to "to_print".
Each cell then can opt-in, whether it needs to be printed.
Only if no cell opts-in, it will be skipped.

Instead of re-fetching the UUID each time with a D-Bus call,
cache/memoize it.
On my system, this improves
$ make check-local-clients-tests-test-client
from 20.9 to 20.4 seconds (- 2.6%). That is not stellar, but noticible
enough to warrant this simple change.
Instead of letting each nmcli run write an individual .expected file,
combine the output of multiple runs in one file (per test).
Advantages:
- since there is a very large number of tests, having a file for each
tests is cumbersome. For example, since they are all added to
$(EXTRA_DIST) (and since we use non-recursive make), autoconf can
easily hit a length limit when processing all the file names.
- previously, whenever we added tests, all .expected files shifted
and the diff was large. Now, there is a chance that the diff is
smaller and more accurate.
